When our zoo opened in 1965 it had lots of storybook features, hence Mother Goose Pond, our former pig exhibit with houses made of straw, wood and bricks, etc. "Little Poof" was from a kids book and was originally just the tiny engine that kids could play in. When we did some major renovations to the area around the train station we moved the little engine & added a couple of cars so more kids could play. The train itselfe is called the Kuhneville Express after the family that originally donated money to build the area. And no, words often don't mean the same here!
